| Abstract: | We describe a electrochemically driven molecular shuttle, in which shuttling takes place by means of fullerene radical‐anion recognition that results in a very low operation potential (E1/2=?0.580 V vs. decamethylferrocene). This has been achieved by introducing positive charges on the macrocycle, which strengthen the existing π–π interactions between the macrocycle and the electrogenerated fullerene radical anion by means of an electrostatic component. In addition, the synthesis of such a molecular shuttle has been accomplished by developing a new synthetic approach that exploits the controlled translocation of the macrocycle as a selective protecting group. |
